| 14:17:04 | shaohe_feng | Sundar, So the VANS can also be used for os-acc and cyborg driver, right? | |
| 14:17:19 | Sundar | Yes. | |
| 14:17:24 | shaohe_feng | great. | |
| 14:18:10 | shaohe_feng | seem Coco is not on line, we can discuss it by mail. | |
| 14:18:18 | shaohe_feng | night xinran__ | |
| 14:18:47 | shaohe_feng | LI_Liu, wangzhh, dolpher any suggestion on this topic? | |
| 14:20:26 | shaohe_feng | jiangguocai, evening | |
| 14:20:29 | wangzhh | Sorry. I lost connection just now. | |
| 14:20:32 | LI_Liu | Regarding the driver/agent API. I don't have much comments, one thing needs to be aware of is to make sure the data structure from driver is understandable by the agent | |
| 14:20:36 | shaohe_feng | and welcome. | |
| 14:21:06 | LI_Liu | e.g. Physical_Functions/Virtual_Functions | |
| 14:21:16 | shaohe_feng | LI_Liu, agree. | |
| 14:21:20 | LI_Liu | but not Deployables tho | |
| 14:21:25 | wangzhh | Yep. Agree. | |
| 14:22:16 | Sundar | Li_Liu: "but not Deployables tho" Can you elaborate on what you mean here? | |
| 14:22:28 | jiangguocai | hello everyone | |
| 14:22:31 | LI_Liu | Other than that, Driver can do pretty much w/e they feel like to do | |
| 14:22:52 | dolpher | Using oslo version object would be part of that? I think using ovo is good | |
| 14:23:22 | LI_Liu | Deployable is a data type not exposed to others out side of Cyborg DB/Object | |
| 14:23:23 | wangzhh | Do we need extra ovo for driver data structure? I mean could we reuse the exists acc and deployable? | |
| 14:24:16 | Sundar | Wangzhh: The existing objects exchanged by driver/agent should be come OVOs. That basically means the fields become well-defined, a version and a namespace get added | |
| 14:24:42 | shaohe_feng | and will rebase on LI_Liu's original client. | |
| 14:24:45 | Sundar | We could use the same namespace for all driver/agent objects, but whether that should be the same namespace as for os-acc plugin is something we can discuss | |
| 14:25:47 | Sundar | Li_Liu: I think you are saying Deployables need not be converted into OVOs. Sounds reasonable, | |
| 14:26:00 | Sundar | Sure | |
| 14:26:53 | LI_Liu | hmm But Deployable is super class of Physical_Function and Virtual_Functions | |
| 14:27:15 | wangzhh | SundarLet me see. Something is different between them, | |
| 14:27:22 | shaohe_feng | Sundar, OK, can you send an email or spec to elaborate how driver/agent use VANs? | |
| 14:27:36 | wangzhh | I'll add comment later in the spec. | |
| 14:28:04 | shaohe_feng | jiangguocai, any things want to talks about the placement. | |
| 14:28:50 | Sundar | shaohe: yes, I will expand os-acc spec and driver/agent spec to address that | |
| 14:29:02 | shaohe_feng | xinran__, is here. she know well about how placement works during the how process in openstack. | |
| 14:29:25 | shaohe_feng | Sundar, good thanks. | |
| 14:30:02 | shaohe_feng | any others want to discuss on placement? | |
| 14:30:11 | wangzhh | Li liu, we should have a clear name for the acc unit(deployable). Now, we use the deployable which will make user confused. | |
| 14:30:33 | LI_Liu | well, I know.. | |
| 14:31:23 | LI_Liu | But given that we should not let them know at the first place anyways... | |
| 14:32:02 | shaohe_feng | #action Sundar will expand os-acc spec and driver/agent spec to address VANs usage | |
| 14:33:29 | wangzhh | IMHO, If we had doc to explain it, I think call it deployable is OK. :) | |
| 14:33:32 | xinran__ | sorry I lost the connection for a while | |
| 14:33:53 | Sundar | Li_Liu and wangzhh: trying to understand the discussion here. I think you are saying this: "PF/VF objects are inherited from Deployables, but PF/VFS are exchanged between driver/agent. So, how can we make PF/VFs into OVOs, but not Deployables? " Is this right? | |
| 14:34:53 | Coco | #info Coco | |
| 14:35:04 | LI_Liu | Yes, that's kinda what we meant | |
| 14:35:06 | shaohe_feng | Coco, evening. | |
| 14:35:15 | xinran__ | jiangguocai: plz feel fee to let us know if you wanna ask something about placement | |
| 14:35:24 | xinran__ | #info xinran__ | |
| 14:35:40 | jiangguocai | shaohe_feng: l reviewed your code about placement client. but not called in other code | |
| 14:35:56 | LI_Liu | #info Li Liu | |
| 14:36:46 | wangzhh | Hi, xinran__, PLZ look at the comment in line. I have the same question. | |
| 14:36:56 | Sundar | Li_Liu: The PF/VF stored in the DB will be a different object than the OVO exchanged between drivers/agent for PF/VF. The latter is exposed, the former is Cyborg-internal. | |
| 14:37:04 | jiangguocai | shaohe_feng: do you want to design it for a service？ | |
| 14:37:21 | edleafe | #info Ed Leafe | |
| 14:37:28 | shaohe_feng | jiangguocai, no, it just a lib | |
| 14:37:30 | wangzhh | Welcome! | |
| 14:37:35 | shaohe_feng | morning efried | |
| 14:37:54 | efried | shaohe_feng: ō/ | |
| 14:38:07 | Coco | what's the topic now? can't catch much of your discussion. | |
| 14:38:07 | LI_Liu | Sundar: Thank you for the clearification | |
| 14:38:08 | efried | We having a meeting? | |
| 14:38:31 | xinran__ | wangzhh: which comment? Sorry, I just lost the connection... | |
| 14:39:27 | wangzhh | https://review.openstack.org/#/c/585146/ | |
| 14:39:35 | shaohe_feng | edleafe, we have add many amazing features theses days, os-acc, cyborg-client. will be ready for the interaction with nova in next release. | |
| 14:39:36 | wangzhh | Here. | |
| 14:39:55 | shaohe_feng | edleafe, and we need your help on nova side. :) | |
| 14:39:58 | Sundar | efried: yes, this is the Cyborg drivers meeting, which happens Mondays 7 am PDT. | |
| 14:40:34 | edleafe | shaohe_feng: My involvement with the Nova project has been greatly reduced. You will probably have more success with efried | |
| 14:40:52 | xinran__ | wangzhh: let me have a look | |
| 14:41:26 | shaohe_feng | edleafe, ok, thanks. | |
| 14:42:04 | shaohe_feng | Sundar, have talked with efried on nova interaction? | |
| 14:42:44 | Sundar | shaohe: the entire os-acc spec discussion is an extended conversation with efried :) | |
| 14:43:05 | shaohe_feng | these days we are so busy, sorry for the delay. | |
| 14:44:28 | shaohe_feng | but any one wants to learn more about how placement work during the cyborg/nova interaction. can discuss with xinran__ | |
| 14:44:54 | Sundar | shaohe: NP. | |
| 14:45:01 | Sundar | efried: Saw your reply in the spec. I can explain the Cyborg driver model. Would you be available at 9 am PDT? | |
| 14:45:02 | LI_Liu | I have to drop guys. Have a good night/day | |
| 14:45:26 | shaohe_feng | LI_Liu, have a good day. Bye. | |
| 14:45:35 | wangzhh | Bye, Uncle li. | |
| 14:45:49 | efried | Sundar: I.e. 1:15 from now? Yes, wfm. | |
| 14:46:22 | shaohe_feng | Coco, you miss the refacor of driver return data. Sundar suggested to use his VANs model. You can discuss it with him about more details. | |
| 14:46:28 | jiangguocai | shaohe_feng: for driver to call？can you take a simple for us, thanks | |
| 14:46:56 | shaohe_feng | jiangguocai, yes. will come out soon. | |
| 14:47:03 | Sundar | Great, efried. I'll catch you on #openstack-nova | |
| 14:47:15 | efried | Sundar: Here is probably more appropriate. | |
| 14:47:28 | efried | unless it will interrupt something else. | |
| 14:47:38 | xinran__ | wangzhh: you mean how cyborg report the resource to placement? | |
| 14:47:48 | shaohe_feng | jiangguocai, can you discribe your drivers? Let me give you a solution. | |
| 14:47:50 | shaohe_feng | here. | |
| 14:48:03 | Coco | OK, I will talk with Sundar about more details of the VANs model. | |
| 14:48:49 | wangzhh | xinran__, Yes. I want to know the data structure and how we call it. | |
| 14:49:40 | shaohe_feng | welcome jiapei | |
| 14:50:19 | jiapei | hey, morning Shaohe | |
| 14:50:33 | shaohe_feng | wangzhh, do you just pass the physical GPU to VM? | |
| 14:50:44 | shaohe_feng | nvdia? | |
| 14:50:47 | wangzhh | Yes。 | |
| 14:51:38 | shaohe_feng | One card is one GPU? | |
| 14:52:06 | wangzhh | Yes. No share mode now. | |
| 14:52:21 | xinran__ | wangzhh: you can check the provider_report in resource_tracker.py | |
| 14:54:32 | xinran__ | wangzhh: oh sorry these code is not in this patch | |
| 14:54:56 | xinran__ | wangzhh: let me check and tell you after meeting | |
| 14:55:06 | shaohe_feng | wangzhh, that's a not a complex use case. | |
